Following the success of “Superman,” next up for DC Films co-boss James Gunn is the second season of his “Peacemaker” HBO Max series, which returns next week.

Back in January of 2024, Gunn confirmed there were not plans to bring back Margot Robbie's Harley just yet. And while he expressed interest in working with her again, it's possible that her tenure as the beloved DC antihero has come to an end.

Could Margot Robbie return as Harley Quinn in James Gunn's new DC universe, or have this bird's wings been clipped? The new co-head of DC Studios (alongside Peter Safran) has been busy rebooting the comic book company's onscreen world with an entire slate of movies and shows that kicked off with last month's Superman (written and directed by Gunn).
